I have a CaseIh Trimble 750 and Ezsteer. It has worked very well in the past to plant with. Every year in the spring I take it to my dealer to get updated. This year it was updated in early April and I also upgraded from Omnistar to Rtx. When I was able to start planting in late May the Ezsteer would weave until I stopped it. Played phone tag with the dealer but needed to get planting done. The lights on the 750 appear to be working good on the ab lines.

Any thoughts what is going on?  Thanks, Jim
